DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 to 3, the present invention relates to a transmission structure for an ornament; the ornament 11 comprises a plurality of still ornament 29 and rotative ornaments 25 and 40; the still ornament 29 is mounted on a still disk 14; the rotative ornament 25 is mounted on a ring-shaped plate 24 of a round member 31; the rotative ornament 40 is mounted on a circular surface 28 of a rotative disk 13. A driving force is generated with a music generator 17, and the driving force is to be transmitted to the ring-shaped plate 24 of the round member 31 through the small gear 19 of the driving unit 18 and the inner gear 20 of the round member 31 so as to have the rotative ornament 25 to rotate. The gear 23 of the rotative ring 15 under the round member 31 can drive a gear train 26 so as to actuate the rotative ornament 40 on the rotative disk 13 to move.

Referring to FIGS. 2 and 3, the transmission structure includes a base disk 12 with a salient ring 73, and a rotative ring 15 is mounted on the salient ring 73; the inner surface of the rotative ring 15 is in close contact with the outer surface of the salient ring 73. The inner surface of the rotative ring 15 has an inner-ring shoulder 21, which is used to support the rotative ring 15 upon the same mounted on the salient ring 73. The salient ring 73 is substantially a hollow cylinder, in which a positioning cup 16 is mounted; the upper edge of the positioning cup 16 is furnished with several hooks 22 to be placed on the inner-ring shoulder 21 of the rotative ring 15; the music generator 17 assembled together with a driving unit 18 is fastened in the positioning cup 16 with screws. The hooks 22 of the positioning cup 16 are used to prevent the rotative ring 15 from separating outwards; the salient ring 73 of the base ring 12 is used to cause the rotative ring 15 to rotate.

The top of the driving unit 18 assembled together with the music generator 17 is mounted with a small gear 19 to be engaged with an inner gear 20 in the round member 31. The round member 31 and the rotative ring 15 are connected together as one piece. In addition to providing music, the music generator 17 with the driving unit 18 can drive the small gear 19 so as to actuate the round member 31 and the rotative ring 15 to rotate.

After the rotative ring 15 being mounted on the salient ring 73 of the base disk 12, the round member 31 will be mounted on an outer-ring shoulder 75 of the rotative ring 15 to form into one piece. The top edge of the round member 31 has a ring-shaped plate 24, on which a rotative ornament 25 is mounted; the small gear 19 is engaged with the inner gear 20 in the round member 31 so as to drive the rotative ornament 25 on the round member 31 to rotate. If the top edge of the round member 31 has no ring-shaped plate 24, the inner gear 20 in the round member 31 engaged with the small gear 19 of the driving unit 18 can only provide an output through the driving gear 23 of the rotative ring 15.

The driving gear 23 on the bottom edge of the rotative ring 15 is engaged with one or more gear trains 26 on the outer edge of the base disk 12. The outer edge of the gear train 26 is mounted with a rotative disk 13, and the inner gear 30 on the inner bottom of the rotative disk 13 engages with the gear train 26. The driving force is supplied from the driving gear 23 on the bottom of rotative ring 15, and transmitted through the gear train 26 to drive the rotative disk 13 to move.

The gear train 26 on the outer edge of the base disk 12 includes a plurality of supporting posts 27 mounted thereon. The gear train 26 may include an odd or even number of gears; when the outer edge of the gear train is engaged with the inner gear 30 of the rotative disk 13, the moving direction of the rotative disk 13 can be pre-determined, i.e., in a forward or reverse direction so as to determine the number of gears; a retarding gear train might be used for reducing the rotation speed of the rotative disk 13.

The supporting posts 27 furnished on the base disk 12 are arranged in accordance with the transmission requirement of the gear train 26; if the transmission gear are arranged on a plane, there is at least a gear being mounted between the driving gear 23 on the bottom of the rotative ring 15 and the inner gear 30 of the rotative disk 13, and such gear is an idle gear for transmitting driving force. If the gear train 26 is used as a retarding gear train, the gear train includes at least two gears, in which at least one gear is a retarding gear; the inner edge of the gear engages with the driving gear 23 on the bottom of the rotative ring 15, while the outer edge thereof engages with the inner gear 30 of the rotative disk 13 so as to provide a retarding function upon transmitting the driving force.

Between the two gear trains 26 on the base disk 12, there are several positioning plates 76 with a suitable inner and outer diameters, and height; the top surface of the positioning plates 76 are furnished with a plurality of positioning studs and small round holes 77. By means of the positioning studs and small round holes 77, the still disk 14, the base disk 12, the gear train 26 and the rotative disk 13 are assembled together to form into a transmission structure. The bottom of the inner round surface 79 of the rotative disk 13 is furnished with an inner gear 30, while the upper edge thereof is furnished with a smooth surface smaller than the diameter of the inner gear 30. After the rotative disk 13 is mounted on the outer circle of the positioning plate 76 on the base disk 12, the inner gear 30 will engage with the gear train 26. The inner round surface 79 of the rotative disk 13 has a smooth surface; when the still disk 14 is mounted on the positioning plate 76 of the base disk 12, the lower round surface 80 of the still disk 14 will be in contact with the smooth surface of the inner round surface 79 of the rotative disk 13. When the driving gear 23 on the bottom of the rotative ring 15 transmits a driving force to the gear train 26, the rotative disk 13 will rotate steadily.

Referring to FIGS. 1 to 3 again, the still disk 14 to be mounted on the positioning plate 76 has a circular flat side, on which a beautiful still ornament 29 is mounted; the ring-shaped plate 24 of the round member 31 is glued with a rotative ornament 25. The circular surface 28 of the rotative disk 13 is glued with a rotative ornament 40. After the inner gear 20 of the round member 31 is engaged with the small gear 19 of the driving unit 18 on the music generator 17, the rotative ornament 25 will be driven to move. The other rotative ornament 40 is driven to move by means of the inner gear 30 of the inner round surface 79 of the rotative disk 13 engaged with the gear train 26 of the base disk 12, and by means of the gear train 26 being engaged with the driving gear 23 on the bottom of the rotative ring 15

Under the shaft socket 53 of each body member 41A or 41B, there is a positioning flange 81 for mounting the bottom of the positioning disk 43; the positioning flange 81 can provide a resistant function. The bottom of the body member 41A in the swinging assembly 37 has an open recess 82, which is aligned to the open cut 54 of the positioning disk 43 in the same direction so as to facilitate the small transmission gear 42 under the positioning disk 43 to be engaged with, through such open cut 54 and open recess 82, the retarding gear train 33 or the gear train 26. The positioning disk 43 between the two body members 41A and 41B has a suitable thickness, and has an axle hole 44, while the bottom thereof has an open cut 54; the axle hole 44 is for receiving a short shaft 83 of the small transmission gear 42; the short shaft 83 is to be plugged into the shaft hole 84 of the eccentric rod 45. After the positioning disk 43 assembled together with the two body members 41A and 41B, the disk 43 will be fastened under the bottom of the positioning flange 81. After the positioning disk 43 with the small transmission gear 42 is mounted in the recess part 36 of the flat plate 32, the small transmission gear 42 will, through the open cut 54 and the open recess 82, engage with the retarding gear train 33. The short shaft 83 passing through the axle hole 44 of the positioning disk 43 is connected with the shaft hole 84 of the eccentric rod 45, and the small transmission gear 42 can drive the eccentric rod 45 to rotate.

The eccentric rod 45 has an arm plate 46 having a shaft hole 84 on one end thereof, while the other end thereof has a short post 47; the shaft hole 84 of the eccentric rod 45 is to be mounted over the short shaft 83 penetrated through the axle hole 44; the short post 47 is mounted in a guide channel 52 of the guide plate 51 under the swinging rod 48. The eccentric rod 45 is to be rotated together with the small transmission gear 42; the short post 47 on the arm plate 46 can move circularly to cause the swinging rod 48 to swing back and forth.

The swinging rod 48 in includes branch shafts 49, a round axle 50, and a guide plate 51; the branch shafts 49 are furnished on both sides of the round axle 50, and is pivotally connected with the shaft sockets 53 of the two body members 41A and 41B. The round axle 50 extends upwards from the branch shafts 49; the round axle 50 is connected with a connecting sleeve 56 mounted with an ornament. The lower end of the round axle 50 is connected with a guide plate 51, of which the bottom has a guide channel 52 to be coupled with the short post 47 of the eccentric rod 45. The branch shafts 49 are used as the shaft of the swinging rod 48. The small transmission gear 42 can drive the short post 47 on the eccentric rod 45 to move circularly so as to cause the swinging rod 48 to swing back and forth.

Before the swinging assembly 37 being assembled together with the two body members 41A and 41B, the short shaft 83 of the small transmission gear 42 penetrates through the positioning disk 43, being connected with the eccentric rod 45; the swinging rod 48 is pivotally connected, by means of the branch shafts 49, with the shaft sockets 53 of the body members 41A and 41B. The guide channel 52 of the guide plate 51 is pivotally mounted to the short post 47 of the eccentric rod 45. After the two body members 41A and 41B, the swinging rod 48 and the positioning disk 43 are assembled together as one piece, an independent swinging assembly 37 is formed. When the small transmission gear 42 of the swinging assembly 37 rotates, the circular motion of the eccentric rod 45 will be transformed into a swinging motion of the swinging rod 48 so as to have the swinging ornament 85 on the round axle 50 swung.

The swinging ornament 85 and the swinging assembly 37 are connected together by means of a connecting sleeve 56 having a round hole 57. The bottom surface of the connecting sleeve 56 and the swinging ornament 85 are set on one level; the round hole 57 of the connecting sleeve 56 is mounted on the round axle 50; the swinging ornament 85 will swing with the swinging assembly 37 simultaneously.
